Solution Overview
Problem
Conventional vacuum cleaners are inefficient and time-consuming when cleaning narrowly structured areas, such as keyboards, due to their design limitations.
Innovation Solution
A hand-held vacuum cleaner with a switching mechanism that allows airflow to switch between an air outlet and an air blowing vent, enhancing cleaning effectiveness by directing airflow into narrow gaps and improving dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional vacuum cleaner design is used, then the device structure is simple, but the cleaning effect on narrowly structured places is poor and it takes a lot of time and effort
Solution Approach 1:
The patent implements a switching mechanism that dynamically changes the airflow path configuration. The switchable connection between the air blowing vent and air inlet allows the vacuum cleaner to adapt between different cleaning modes (narrow space cleaning vs. general cleaning), resolving the contradiction by making the device structure dynamically adjustable rather than statically simple or complex
Solution Approach 2:
The patent adds an air blowing vent that can serve multiple functions: blowing air into narrow gaps for cleaning and also being connected to the air inlet for dust collection. This multi-functional design allows a single device to handle both narrow space cleaning and general cleaning tasks, improving productivity without requiring entirely separate devices
2Productivity
If airflow is directed into narrow gaps for cleaning, then the cleaning effect on narrowly structured places is improved, but the dust collection capability may be reduced
Solution Approach 1:
The switching mechanism enables dynamic reconfiguration of the airflow path. When cleaning narrow spaces, the air blowing vent connects to the air inlet to blow dust into the suction path. When performing general cleaning, the system can switch to normal suction mode, ensuring dust collection capability is maintained across different operating conditions
Solution Approach 2:
The air blowing vent acts as an intermediary element that can either blow air directly for cleaning or connect to the air inlet to serve as a dust collection entry point. This intermediary structure resolves the contradiction by providing a flexible pathway that serves both blowing and suction functions depending on the cleaning task
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design facilitates better cleaning of narrow spaces with improved efficiency and effectiveness, reducing the time and effort required for cleaning such areas.
Implementation Method 1
an airflow entering from the air inlet flows through the dust cup and the electrical motor, and switchably flows out through at least one of the air outlet and the air blowing vent
